Maku gave the warning on Saturday while addressing youths in Wakama Villege of Nasarawa-Eggon Local Government Area (LGA) of the state.
He said that he had already written a petition to the appeal panel set up by the national headquarters of the party challenging the outcome of the primaries.
He mentioned the irregularities that occurred during the primary to include shortchanging of delegates names in many LGAs, intimidation and threatening of delegates, among others.
According to him, the fraud committed in the recent PDP governorship primaries in the Nasarawa state is worse than the one committed at party’s primaries in the state in 2007.
He said that he would take a decision and seek for peoples mandate directly if steps were not taken to correct these anomalies in the next one week.
“Since they think they can shortchange the names of delegates and intimidate them, we will see how they can shortchange and intimidate the members of the public,” he said.
He vowed to move on with his ambition to contest the governorship seat of the state in 2015 and advised all those who thought they could deny the state of good leaders to have a rethink.
Maku promised that he would restore peace in the state within six months and reposition the state for total transformation if elected as governor in 2015.
He, however, urged all his supporters to support the re-election of President Goodluck Jonathan in 2015 for consolidation of development of the country.
Maku said that Jonathan was one of the best presidents the country had ever produced using all parameters of developments.
He called on his supporters to remain calm and law abiding, stressing that he would make decisions known publicly in the next week.
